Grey‐Body Factors and Absorption Cross‐Sections of Scalar and Dirac Fields in the Vicinity of Dilaton‐De Sitter Black Hole

open access: yesFortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

One-loop finiteness in higher-derivative 6D, 𝒩 = (1, 0) super Yang-Mills — hypermultiplet system

open access: yesJournal of High Energy Physics
We employ the harmonic superspace methods to study a six-dimensional 𝒩 = (1, 0) supersymmetric gauge theory with higher derivatives coupled to a hypermultiplet in the adjoint representation.

Simultaneous Bosonic and Fermionic T‐Dualization of the Type II Superstring Theory—Buscher Approach and Double Space Representation

open access: yesFortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.

Superconformal index for N=3 ADEˆ Chern-Simons quiver gauge theories

open access: yesNuclear Physics B, 2022
We compute superconformal indices for N=3 ADEˆ Chern-Simons quiver gauge theories with a product gauge group ∏iU(N)i, using the method of supersymmetric localization. We also perform a large N analysis of the index.

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

Localization and Dualities in Three Dimensional Superconformal Field Theories [PDF]

open access: yes, 2012
In this thesis we apply the technique of localization to three-dimensional N=2 superconformal field theories. We consider both theories which are exactly superconformal, and those which are believed to flow to nontrivial superconformal fixed points, for

The holographic dual to supergravity instantons in AdS5 × S5 /ℤk

open access: yesJournal of High Energy Physics, 2019
We investigate the holographic dual to supergravity instanton solutions in AdS5 × S5 / ℤk, which are described entirely in terms of geodesics on the AdS moduli space.

Study on Approximate C∗‐Bimultiplier and JC∗‐Bimultiplier in C∗‐Ternary Algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
An additive‐quadratic mapping F:A×A⟶B is one that adheres to the following equations: Fr+s,t=Fr,t+Fs,t,Fr,s+t+Fr,s−t=22Fr,s+Fr,t. This paper leverages the fixed‐point method to investigate C∗‐bimultiplier and JC∗‐bimultiplier approximations on C∗‐ternary algebras. The focus is on the additive‐quadratic functional equation: Fr+s,t+u+Fr+s,t−u=2222Fr,t+Fr,

Gauge Theory and Supergravity Duality in the PP-Wave Background [PDF]

open access: yes, 2005
We test the matrix theory conjecture in the pp-wave by studying two-body interactions between gravitons and membranes. We compute the one-loop effective potential of matrix theory and compare it to the light cone Lagrangian of linearized supergravity. We

Analysis of Ward identities in supersymmetric Yang–Mills theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
In numerical investigations of supersymmetric Yang–Mills theory on a lattice, the supersymmetric Ward identities are valuable for finding the critical value of the hopping parameter and for examining the size of supersymmetry breaking by the lattice ...
